This is definitely a newbie question, but I bought a two tap kegerator and it was set up to use the sankey couplers and the kegs I bought from Northern Brewer are set up to use ball locks. I prefer the ball locks and changing the CO2 tank connects to a ball lock isn't a problem, but the kegerator's lines that run up to the tap are for sankey couplers. Does anyone have a suggestion on what I should do/buy/change to connect the tap lines to the kegs?

I bought the hardware at NB (it's my LHBS) and just cut off the beer line right at the Sankey fitting. Slipped a hose clamp on the line, squeezed in the barbed part of a swivel nut, then tightened the hose clamp. Tightened the swivel nut onto the ball lock fitting, and done.
